Pinkie Pie's family abusive? · 11:53pm Jun 10th, 2022
This is a popular head cannon in some circles. Honestly I just don't see it.
If anything, given the send off they give Pinkie, I think they apprenticed her off so she could live out her role early because they were so excited for her.
And her overly peppy act, hiding her sadness and other emotions, is her poor understanding of trying to live up to her Cutie Mark.
